Pls help

Answers

Answer 1
20 ft. Because you round to the nearest tenth, so sorry if I’m wrong
Answer 2

The distance between the bottom of the ladder to the bottom of the building is 24 feet.

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given that If you place a 28-foot ladder against the top of a 15-foot building,

We need to find how many feet will the bottom of the ladder be from the bottom of the building.

This can be found by using the pythagoras theorem.

Let the ladder be the hypotenuse and wall be the opposite sides of triangle. We need to find the adjacent side.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides

15²+x²=28²

225+x²=784

x²=784-225

x²=559

Square root on both sides

x=23.64

x=24 feet.

Hence, 24 feet is the distance between the bottom of the ladder to the bottom of the building

Solve for x: 15x + 121 = 256

Solve the inequality: 4x + 8 > 2x - 10

Solve for x: 5x + 7 = 42

Answers

Answer:

Step-by-step explanation:

15x + 121 = 256 the answer is x = 9

4x + 8 > 2x - 10 the answer is x > -9

5x + 7 = 42 the answer is x = 7

Answer:

x=9, x>-9, x=7

Step-by-step explanation:

[tex]15x + 121 = 256 \\ 15x = 256 - 121 \\ 15x = 135 \\ \frac{15x}{15} = \frac{135}{15} \\ x = 9[/tex]

[tex]4x + 8 > 2x - 10 \\ 4x - 2x > - 10 - 8 \\ 2x = - 18 \\ \frac{2x}{2} = \frac{ - 18}{2} \\ x > - 9[/tex]

[tex]5x + 7 = 42 \\ 5x = 42 - 7 \\ 5x = 35 \\ \frac{5x}{5} = \frac{35}{5} \\ x = 7[/tex]

Find all roots of the polynomial function f(x) = 2x^4-x^3-13x^2+5x+15

Answers

Answer:

Roots are :  1, -7 and -7

Step-by-step explanation:

When we put x = -1 in F(x) it is equal to 0

Thus, (x + 1) is factor of given function.

When we divide F(x) by (x + 1) it gives the value (x² - 6x - 7)

factorizing the work  x² - 6x - 7 by middle term splitting.

> x² - 6x - 7 = x² - 7x + x - 7

>  x(x - 7) + 1(x - 7)

>  (x + 1) (x - 7)

then,  x³ - 5x² - 13x - 7 = (x + 1)(x + 1)(x - 7)

x = -1, -1, 7 the factor.

It is symmetric and has a peak at 3.
It is symmetric and has a peak at 4.
It is not symmetric and has a peak at 3.
It is not symmetric and has a peak at 4.

Answers

Answer:

The correct answer is A.

Remember summetric means: made up of exactly similar parts facing each other or around an axis; symmetrical. And the peak or highest part is on the 3.

Hope it helps!!

The statement which best describes the shape of the data is option A. It is symmetric and has a peak at 3.

What are Symmetric Data Plot?

A data plot is said to be symmetrical if the two sides of the data plots or the distribution are the mirror images of each other.

Given is a data plot which shows the number of items in the basket of some shoppers.

There is a dot plot with integers from 1 to 5.

From the dot plot it is clear that, the dot plot is symmetrical since the middle number 3 divides the plot in to two equal ways.

In other words, it can be divided in to mirror images.

Peak of the dot plot is the number with the highest count.

Here 3 is having the highest counts of items in the basket.

So dot plot has peak at 3.

Hence the dot plot is symmetric and has a peak at 3.
